Zunism

Zunism was a pagan religion that originated in Afghanistan. Zun, the Giver of Justice, was the sun-god originally worshipped by the Zunbil dynasty in Afghanistan. Zun embodies wisdom, power, fire, and the light that drives away the night.

History
The religion of Zunism may have originated in Afghanistan, but the religion spread north to the Northern Zhao dynasty of China, a dynasty of Uyghurs that ruled over northern China. The ruling House of Zhao's worship of Zun decreased the opinion of their predominantly-Manichaean and Tengri vassals.

In Zunism, priests could marry, but Zunists were inferior at conversion and were vulnerable to non-pagan missionaries. In Zunism, rulers could take up to three concubines.
